My Verizon FiOS is fibre-optic to a box on the outside of my house. There the signal is converted to 4 voice lines, one ethernet line, and a co-ax for television ("cable"). I actually use only one voice line, but I did use two for a while. And I do not watch TV, so I do not need that. The ethernet line goes to a Verizon-supplied router that is hard-wired to my main computer, to a littlle Windows10 computer, and my UPS that keeps in occasional touch with the UPS vendor (APC).You have fibre to the house and aren't using 1 Gbit? Can we swap houses please? "Wouldn't benefit" WTF? Everything can go faster. What's a FiOS? |

When I was working as an electrician's helper, I saw one on the problems with aluminum wire. Ahh! Yes. I used to work in a very fancy office building designed by Eero Saarinen who was a pretty good architect, but there were a few screw-ups. Aluminum wire for the main feeders, though copper to each office and each laboratory. I used the services of the plant department when installing a new computer for our work. And the main engineer in the plant department and I became pretty good friends. Several times a year he went to each and every power panel where the aluminum wire was present and measured the temperature of each connection with an optical infra-red pyrometer. Anything that was too hot got fightened or the wiring replaced. https://www.midcenturyhome.com/eero-saarinens-bell-labs-holmdel-complex-collaboration-reignited/ |

Ahh! Yes.Ahhh, French electrics. Like in my car :-/ |

You have fibre to the house and aren't using 1 Gbit? Can we swap houses please? "Wouldn't benefit" WTF? Everything can go faster. What use is 1 GBit (my NIC will go that fast) to me when the servers at the other end, such as WCG, only go around 40 to 60KBytes per second. Increasing my peak rate from 75 Megabits/ second up to 1000 Megabits per second will make no difference at all. Everything at my end could go faster but the throughput is no faster than the slowest link in the chain, and I somehow do not think from here to Canada (where WCG is now located) wil go any faster no matter how fast my end is. Sending their signals through US border control incurs huge delays (just kidding). FiOS is a data service from Verizon that is fibre-optic to the home. They offer different speeds for different prices, but I am paying only for 75 Megabits/second up and down. |

FiOS is a data service from Verizon that is fibre-optic to the home.I misread that as to the throne! (Toilet if throne only makes sense in the UK). |

The worst of all is with fine multistrand copper wire that has its end soldered to a `nice` blob then screw fixed , it wont stay fixed for long :-(Just twisted up also comes loose, so does non-stranded solid copper. Maybe the screw undoes with vibration? It could be glued? Or is the wire moving or compressing? Big current stuff here is done up with two or more grub screws in a row. And you shouldn't have the wire under any tension so it pulls out when it gets loose. Gah, that sentence is so untidy, this stupid forum removes my double spacing between sentences. And yet it can't get the line spacing right.... |

I assume you don't only use WCG? Most places will go way faster than your current connection. Especially piratebay! My favorites now, in order, are ClimatePrediction, WCG, Rosetta. I also am doing universe and milkyWay to soak up unused processors because ClimatePrediction sent me only one work unit in the last 4 months (Nov 7) that bombed out with invalid theta. 4 other users bombed on that work unit too. Except for that one, the last work unit I got from CPDN was at the end of July. I had about an 8-month gap in WCG work units. And Rosetta does not keep up with my machine either. I used to do Seti@home and Malaria, but they are gone. IIRC, none of those go faster than my connection. |

I also am doing universe and milkyWay to soak up unused processors because ClimatePrediction sent me only one work unit in the last 4 months (Nov 7) that bombed out with invalid theta.They're planning loads of new work very shortly, definitely for Linux, maybe also Windows under Virtualbox. I see you have a machine running each. 4 other users bombed on that work unit too. Except for that one, the last work unit I got from CPDN was at the end of July. I had about an 8-month gap in WCG work units. And Rosetta does not keep up with my machine either. I used to do Seti@home and Malaria, but they are gone.I can max out all my machines with WCG. Sometimes I can't get enough GPU work, but only 1/4 of the time. All I changed was to make Boinc auto-retry downloads every 30 seconds, and to get 1+0.25 days buffer. IIRC, none of those go faster than my connection.Surely you do other things on the internet besides Boinc? |

Store at least 0.50 days of workFor more than a couple of projects, yes. The whole idea of a cache is to keep your system busy if a project has issues, and you are attached to only that project. The odds of all your projects having issues at the same time with that many projects is bugger all, so there is no need for a cache. With more than a couple of projects, Store at least 0.05 days of work and Store up to an additional 0.01 days of work is plenty, and it means your Resource share settings will be met, much, much sooner.

For more than a couple of projects, yes.I have about 15 projects, but I only run about 4 at a time, and sometimes half those are ones with rare work. So I have a big cache so I get some of the rare work instead of just the other projects filling in. |

Store at least 0.50 days of work You think odds of my projects having issues at the same times are "bugger all?" I have that problem right now. No work units from CPDN since end of July, No work units from Rosetta in about a week. Spotty work from WCG. Having a queue of about a week might take care of Rosetta and now (after six months) WCG. But I do not like that. I much preferred when all these projects supplied work units whenever my Boinc-client asked for it. |

That highly depends on wether you ask for CPU or GPU work and also on your GPU, I'd get there at least 9.5 minutes of work for my GTX 275.That and backup projects should be set to 0% and not something like 0.xx%.Can't do that with Milkyway, you get 40 seconds of work. . |

So I have a big cache so I get some of the rare work instead of just the other projects filling in.I follow a different strategy: projects with rare work or overloaded servers (so in my case WCG & Rosetta) have obviously more than enough computing ressources at the moment, so i set them to NNT and allow new work from those, that can offer continuous supply with work, i.e. they actually need more computing power than they currently get. . |

That is a very interesting strategy. I must think more about it.Well, it has lots of advantages, for myself and the projects: - I don't need to watch BOINC too carefully or even spend my time on pressing the retry button, forcing additional scheduler requests etc. - I don't add load to already overloaded project servers - I don't "steal" work from unattended computers without (working) backup projects, so less idle computers, more science done Of course there are some limits for this strategy, Moo! for example was the last BOINC project supporting my HD3850, so even if it would have some issues, there was simply no other project to which I could move that GPU (except crunching directly for distributed.net of course). Users of for example Macs with Apple CPUs might face similar issues. But a standard x86_64 CPU running Windows or Linux can be moved nearly to any project. . |

My GTX 1650 does Milkyway task in about 6 minutes. That feeling when 2019 GPU is slower than 2013 gpu. |
